Intestinal stroke is a common name for acute ischemic enteropathy, which is an ischemic disease of the intestinal wall caused by acute insufficiency of blood perfusion in the intestine due to various reasons, and is most common in the elderly, with about 90% occurring over the age of 60. In recent years, due to changes in the environment and diet, atherosclerosis has gradually become one of the main causes of death in the elderly, and is also the main cause of “intestinal stroke”. Atherosclerosis does not only occur in the heart and brain vessels, but also has a systemic impact on the body. With the aggravation of the disease, the arteries in the abdominal cavity become sclerotic, especially the superior and inferior mesenteric arteries, which are extremely important for the blood supply to the intestine. ”The main clinical manifestations are sudden and severe abdominal pain and blood in stool, and other common symptoms are bloating, diarrhea, nausea and vomiting. In addition, some manifestations such as “feeling of fullness after meals, discomfort or vague pain in the upper abdomen, lasting 1~2 hours each time”, “symptoms aggravated and prolonged after intake of fatty food or full meals” can be regarded as the “signs” before the attack. signs” before an attack. Prevention of “intestinal stroke” should be: 1, as far as possible to reduce the causes: prevention and control of atherosclerosis, reasonable diet, less animal fat, quit smoking and alcohol, weight control, moderate physical activity, emotional cheerfulness. 2.Strengthen the awareness of prevention: If you often feel abdominal distension and hidden pain after meals, take digestive drugs that are ineffective and recurrent, and have a tendency to lose weight, you should go to the hospital promptly and take necessary measures to control acute intestinal ischemic attacks. 3, regular physical examination: check the lipid composition, blood rheology and other items, especially platelet electrophoresis. Depending on individual symptoms, ultrasonography, abdominal plain film, barium imaging, CT and MRI can be done selectively for early detection or exclusion of “intestinal stroke”. In addition, patients with a history of atrial fibrillation should try to control their heart rate at 60 to 70 beats per minute when they are calm; patients with tachycardia should take drugs to reduce thrombus dislodgement; elderly people with recurrent intermittent abdominal pain and blood in the stool should have selective angiography to understand the site and extent of ischemia and selectively remove the diseased intestinal segment when they are in good health to avoid future accidents due to hemorrhage. .
